Does anyone know of a decent exhaust system/back box with a nice grunt to it for a 09 520d msport ?
I need a bit of a growl out of her !

Also if I go and change exhaust/back box, will she need to be mapped or anything for it ?

Hi Phil,

Eisenmann do very high quality exhausts/mufflers that look and sound amazing, pretty sure there is a YouTube video of a 520D with one installed. I shall have a look for it.

In relation to the remap if you are planning on getting one done I would hold off until you have an exhaust fitted and then do it. If you already have the car mapped and want just a rear muffler you would not really need to remap it. However if you are looking to get a cat back system with less restriction I would be inclined to remap it then to get the best from the exhaust. If you want to PM me your email address I could send you over a price for an Eisenmann rear muffler.

Hope this helps.
